ApplicaticnlNovember 2, 1945, Serial "No."6265352 lhis ihvention relates to mechanical r'means designed 'for vopera-ting rocker-supported bodies.

-lfIhe object -of the Ainvention lis to provide `electrically-controlled means for imparting a rocking motion to rocker-supported bodies, the electrically controlled means being such that the electric circuit to the electric motor of the device, which is in the form of a solenoid, will be automatically completed and broken at predetermined intervals, the circuit-controlling means being operated by the rocking motion of the device.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawing:

Figure l is an elevational View of a rockeroperating means, constructed in accordance with the invention.

Figure 2 is a plan View thereof.

Figure 3 is a perspective view of the operating means.

Figure 4 is a perspective View illustrating the electrical operating mechanism as enclosed by the protecting cover.

Referring to the drawing in detail, the reference character 5 indicates a pair of spaced rockers, on which a body such as a babys crib or the like, is supported.

Mounted between the rockers 5, is a base 6 to which uthe bearing arms 1 are secured, the arms 1 being supported in spaced relation with respect to each other, where they are connected by means of the shaft 8 that is mounted in bearing openings in the upper ends of the arms.

The shaft 9 provides a support for the actuating arm 9, the actuating arm 9 being of a length to extend to a point to contact with the crossbar I0 that connects the rockers 5. The opposite end of the actuating arm 9 has pivotal connection with the solenoid armature or plunger I I, through the medium 'of the yoke I2.

The circuit controlling the action of the solenoid I3 embodies wires I4, I5 and I6, which are in circuit with a suitable source of electricity supply. Arranged in the circuit, and connected with the Wires I4 and I5, is a switch, embodying the contact members I1 between which the blade 2 Claims. (CLIN-126) switch'arrn lr'no've'sin completing 'the circuit to the winding of th'e solenoid.

YlPivotally connected with vthe rswitch 'blade "I8, is a rod I9 which has its threaded upper end 29 extended through an opening formed in the actuating arm 9, loosely mounting the rod with respect to the arm 9. Adjustable stops 2l are arranged on the threaded portion of the rod I9, and by adjusting these stops, movement of the actuating arm 9 with respect to the rod I9, may be regulated.

These stops 2I are engaged by the actuating arm 9 to move the rod I9 and consequently operate the blade switch to make and break the circuit.

In order that arcing of the switch, when blade I8 moves from between the contact arms I1, will be prevented, condenser 22 is provided in the circuit.

The reference character 23 indicates a coiled spring, one end of which connects with the actuating arm 9, while the opposite end of the spring is secured to the base 6. This spring operates to balance and cushion the movements of the arm 9.

A plate indicated by the reference character 24 is fitted over the upper bars 25 that connect the upper ends of the rockers 5. The housing 26 covers the entire electrical equipment, only a portion of the arm 9 extending beyond one end of the cover 2t. Thus it will be seen that due to this construction, the operating mechanism is completely enclosed for safety, and the rockers may be lifted from the base 6 whereby the rockers may be used without mechanical means, if desired.

In the operation of the device, the rockers are tilted downwardly until the cross-bar I0 engages the actuating arm 9. The actuating arm is then carried downwardly into contact with the lower adjustable stop 2l, which moves the rod I9 and switch arm blade I8 downwardly, the blade moving between the contact members I'I, completing the circuit to the solenoid. The plunger of the solenoid is now drawn into the winding, rocking the actuating arm so that the actuating arm moves into engagement with the cross-bar I0, rocking the device by swinging this end of the device upwardly.

This operation will be repeated, causing a con-` tinuous rocking motion of the device.

What is claimed is:

1. In a device of the class described, a body portion embodying a pair of spaced supporting rockers, a cross-bar connecting the rockers, an operating mechanism comprising an actuating arm pivotally mounted between the rockers, electrically-controlled mechanism adapted to operate the arm, embodying an electric circuit, a solenoid in the circuit, means for pivotally connecting the plunger of said solenoid to one end of said arm at a point at one side of the pivot of said arm, a control switch in the circuit, a rod adjustably connected with the actuating arm, at the opposite side of the pivot of the actuating arm and being connected with the control switch, said actuating arm adapted to move upwardly when the solenoid is energized, breaking the circuit to the solenoid, whereby said arm is moved into engagement with the cross-arm tilting the body portion rearwardly, said arm adapted to move in the opposite direction when the body portion swings forwardly, closing the circuit to the switch energizing the solenoid.

2. In a device of the class described, a. body portion embodying a pair of spaced supporting rockers, a cross-bar connecting the rockers, operating means for rocking the body portion, comprising a pivoted actuating arm adapted to en- REFERENCES CITED The following references are of record in the le of this patent:
